Tutorial FRIDA API Set Up and Injection (Hook,Unity)

[Hakuseki]

Thanks, but in my case in NOX player frida can't find any unity native library(il2cpp, libunity, ....)
What should I do?

nothing ya cant do, just wait for a feature from frida or get a rooted devices with arm arch;

we can edit libil2cpp by hex and change some params but we cant connect with frida on API 29 - high protect api

connect is possible, doing something to library? not so much with differ arch: Frida Not Working in Emulator · Issue #378 · frida/frida-core (github.com)

@erucix what kind of device do you use? and do you still using it?

This step:
frida -D 1990303193 -l C:\Users\vladi\Desktop\my_hackable_script.js -f "com.hackedapp.something"

results in the app launching, but quickly closing:

Spawned `com.loadcomplete.slimeidle`. Resuming main thread!
[ONEPLUS A5000::com.loadcomplete.slimeidle ]-> Process terminated
[ONEPLUS A5000::com.loadcomplete.slimeidle ]->
Thank you for using Frida!

Attempting to attach to the process via its pid once its started gives:

Failed to attach: unable to access process with pid 4554 due to system restrictions; try `sudo sysctl kernel.yama.ptrace_scope=0`, or run Frida as root

(Frida_server is running as root, and I'm using the correct version of the server.)

Hours of searching on Google and github have not helped

I am having a problem running frida-server on VMOS, it is having some problems with SELinux ( which I cannot enable nor disable ). The server starts and I can connect, but the commands don't work properly.
Do you have any experience with this?

Hi, I have a question, with this is possible to dump game texts right? but how will be the script to do it? I want to deserialize MessagePack texts of an android il2cpp game

 

[standifordwalsh]

well ya, but nope , you still using offsets , that is really old.

It Should Be Noted That Frida Stuff With Native Libraries Wont Work With Emulators(The Popular Ones NOX/Memu)
(Library Wont Show Up)

Not quite sure TBH becuause I also was trying on NOX, I would anyway suggest to try on physical device

So you would still need il2cpp dumper for unity

well this is the horrible part, I would suggest getting dual boot, and install clean windows within it's clean services without any virtualization

Don't you worry! I am uploading a new tutorial soon where you can use frida on NONE rooted devices! yes yes! and all your problems will be gone

Also as mentioned below, you still going to need to use offsets, anyway if you want to dump your texts, you are always free to decompile APK and grab resources folder where all hardcoded text lays. For variables, I yet not tried to hook to them, only to functions, so you need to still find any kind of a function which somehow uses that text as an argument, hook to it, and print the value you want or change it

Dear friends, I have posted a new tutorial for none rooted android devices, enjoy!
This shall eliminated most of the issues you encounter

 

[Theeundertakeer]

I am too in this situation

You no longer need to worry! check my tutorial on none rooted android device frida usage
